Abstract
Description
Verfahren zu herstellung eines Litzenleiters Die Brfindung bezieht sich auf ein Verfahren zur Herstellung eines Litzenleiters aus mehreren miteinander verseilten Einzeldrähten.Method for the production of a stranded conductor The invention relates refers to a method for producing a stranded conductor from several together stranded single wires.
Litzenleiter werden für häufig bewegte kunststoff- oder gummiisolierte Leitungen, wie z.B. die Netzanschlußleitungen für Bügeleisen, Staulsauger u.dgl. verwendet. Bei derartigen aus vielen Einzelleitern, z.B. 30 bis 60 Stück, bestehenden Litzenleitern werden die Einzele 1 tor bei hohen Fertigungsgeschwindigkeiten mechanisch durch starkes Verwürgen beansprucht und dadurch die mechanischen Eigenschaften der Kupferdrähte sehr nachteilig beeinflußt. Die Bruchdehnung der Einzeldrähte und damit die Biegefestigkeit der Litzenleiter im Eertigfabrikat nimmt ab.Stranded conductors are plastic or rubber insulated for frequently moving Lines, such as the mains connection lines for irons, vacuum cleaners, etc. used. With those consisting of many individual conductors, e.g. 30 to 60 pieces Stranded conductors become the individual 1 gate mechanically at high production speeds stressed by strong choking and thereby the mechanical properties of the Very adversely affected copper wires. The elongation at break of the individual wires and thus the flexural strength of the stranded conductors in the finished product decreases.
Bisher wurde die Verschlechterung der mechanischen Eigenschaften in Kauf genommen, oder - bei höheren Ansprüchen - wurde mit geringer Arbeitsgeschwindigkeit gefertigt. Der Erfindung liegt die Aufgabe zugrunde, ein Herstellungsverfahren für solche Litzenleiter zu schaffen, das die Einhaltung hoher Fertigungsgeschwindigkeiten erlaubt, ohne daß die mechanischen Eigenschaften unzulässig beeinflußt werden. Zu diesem Zweck wird gemäß der Erfindung vorgeschlagen, daß beim Verseilen der Einzeidrähte zentral ein Baden aus Glasseidenzwirn mit verlitzt wird.So far, the deterioration in mechanical properties has been observed in Purchased, or - with higher demands - was done at a slower working speed manufactured. The invention is based on the object of a production method for to create such stranded conductors that maintain high production speeds allowed without the mechanical properties being unduly influenced. to for this purpose it is proposed according to the invention that when stranding the individual wires a bath made of glass silk thread is stranded in the center.
Glasseidenzwirn hat etwa die fünffache Zugfestigkeit eines weichen.Glass silk thread has about five times the tensile strength of a soft one.
Kupferdrahtes und eine Bruchdehnung von ca. 2 ß gegenüber einer mittleren Dehnung von 25 bis 35 Vo (!) bei Kupferdrähten. Glasseide ist außerdem bei 80 % der mittleren Bruchlast noch vollkommen elatisch. Der Faden aus Glasseidenzwirn fängt daher alle auftretenden Zugparameter, die sowohl bei der Litzenherstellunals auch im späteren praktischen Gebrauch des Leiters entstehen, und die die Eigenschaften der Einzelleiter negativ beeinflussen, auf. Daher kann eine hohe Fertigungsgeschwindigkeit eingehalten werden. Eine Vergrößerung des Durchmessers des verlitzten Leiters tritt nicht auf. Da die Einzelleiter etza Durchmesser von 150 bis 250 µm aufweisen, kann ein Faden aus Glasseidenzwirn mit einem Durchmesser von ca. 7 µm zentral in den zu verlitzenden Leiter einlaufen. Er wird dabei in die Hohlräume zwischen den Einzelleitern eingebettet.Copper wire and an elongation at break of approx. 2 ß compared to a medium one Elongation of 25 to 35 Vo (!) For copper wires. Glass silk is also at 80% the mean breaking load is still perfect elatic. The thread out Glass silk thread therefore absorbs all tensile parameters that occur both during the manufacture of the strand also arise in the later practical use of the conductor, and the properties the single conductor negatively affect. Therefore, a high production speed be respected. An increase in the diameter of the stranded conductor occurs not on. Since the individual conductors can have a diameter of 150 to 250 µm a thread of glass silk thread with a diameter of approx. 7 µm in the center of the Enter the ladder to be lost. He is in the cavities between the individual conductors embedded.
Zur Veranschaulichung des Verfahrens ist in der nachstehend beschriebenen Zeichnwiig ein nach dem Vorschlag gemäß der Erfindung aufgebauten Litzenleiter dargestellt. Darin sind die wahren Größenverhältnisse der besseren Anschaulichkeit halber nicht beIbehalten worden. Der Faden aus Glasseidenzwirn ist im Verhältnis zu der Größe der Einzelleiter wesentlich größer dargestellt.To illustrate the procedure is described below A stranded conductor constructed according to the proposal according to the invention is shown in the drawing. The true proportions are not included in it for the sake of clarity been retained. The thread of glass silk twine is in proportion to the size the single conductor is shown much larger.
Der Faden 10 aus Glasseidenzwirn läuft beim Verseilen der Einzelleiter 11 zentral in den Litzenleiter 12 ein und nimmt die sonst auf die Einzelleiter einwirkenden großen Zugkräfte auf.The thread 10 made of glass silk thread runs when the individual conductors are stranded 11 centrally in the stranded conductor 12 and takes the otherwise acting on the individual conductors large tensile forces.
